Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out.
Answer & explanation
Correct answer: option 1
1 2 3 4 5 6 7 8 9 10 11 12 13
A B C D E F G H I J K L M

Z Y X W V U T S R Q P O N
26 25 24 23 22 21 20 19 18 17 16 15 14
THE LOGIC FOLLOWED HERE IS;
1) CXA,
C → (-2) → A
C(3) + X(24) = 27
2) UGS,
U → (-2) → S
U(21) + G(7) = 28
3) JRH,
J → (-2) → H
J(10) + R(18) = 28
4) NNL,
N → (-2) → L
N(14) + N(14) = 28
Thus, CXA is the odd one out.
